Endoscope Cold Light Source is one of the indispensable instruments for minimally invasive surgery. It provides brightness lighting for intracavity observation and inspection. Doctors can visually view the lesion and perform operations. The following editor will introduce the role of endoscope cold light source.
The Role Of Endoscope Cold Light Source:
The basic function of the cold light source of the endoscope is to produce cold light, and various endoscopes using fiber-guided light beams can be provided as the light source part to provide brightness illumination for the observation and inspection of the inner cavity. According to various needs, add corresponding structures to achieve other functions, such as adding air pumps to many medical cold light sources to generate gas, and transmit the gas to the human body through the inner pipe of the endoscope. The human body needs to be inspected. Inflate and pressurize the area to achieve the purpose of opening. At the same time, the air pressure is used to squeeze water to the mirror body to flush the mirror surface and the lesion site for observation, diagnosis and treatment. And according to the adjustment device of the gas volume. In some cases, in order to eliminate the loosening of images due to actions during observation, diagnosis and treatment, the cold light source also adds a high-speed flash.
At present, endoscope cold light sources are roughly divided into ordinary halogen light sources, xenon light sources, and LED cold light sources according to the types of light sources. At present, the most commonly used are xenon lamps and LED lamps. The color of these two light sources is close to daylight, which makes the eyes feel vivid. , But the xenon lamp has a short life span and is often replaced. The LED cold light source has the advantages of small size, long life and high efficiency, and can be used continuously for up to 100,000 hours. In the future, LED light source applications will become mainstream in the lighting field.
